LAPD Alone Can't Fix Skid Row Steve Lopez, Reach the columnist at steve.lopez@latimes.com. This column is dedicated to Jeff Johnson, who took a personal interest in skid row and encouraged me and others at The Times to continue exploring the issues and answers there. Johnson, who was The Times' publisher, considered it one of our more important missions. Johnson was fired this week, and I wish him and his family well.
